But the Aussie believes the lessons learned in 2017 will help him in the future.

“I turned 30 just recently and I feel my 30s will be a lot better than my 20s," said Day.

“I definitely believe I am going to get back.

“I don't just want to get back to No.1, I want to get back and stay there for a long time."

He used the example of Greg Norman who held the No.1 spot for 331 weeks – “that's legendary stuff and that's what I want to be able to do.”

Like many before him, Day found the demands of being world number one took up much of his time, and in the future he’ll be more likely to “say no, politely” to the multitude of requests that come with holding the top spot.

Day’s 2017 campaign was placed on the backburner to some extent as his mother Denning battled cancer. She’s now been given the all-clear and is with Day in Sydney this week.

Day also has a new caddie, having replaced long time mentor Colin Swatton with childhood friend Luke Reardon. Swatton will remain as Day’s coach.

“I think it is going to be good for me,” said Day.

“To be honest I think it is going to free me up a little bit more.

“As a coach I always felt like he (Swatton) was sort of judging me to a certain degree - he may not have been - but that was just how I felt so I felt like I couldn't really go and kind of freewheel out there."
